I just did my first all grain batch yesterday (Orange Wheat Hef). Everything went really well but I got a little bit of a bitter taste when I tried the sweet wort. I did a 10 gallon batch using 8lbs 2 row, 10 lbs White Wheat. 1oz Cascade 60 min boil, 2oz Cascade 5min and 12 orange zested (Some were a little green) These were high quality oranges direct from Gless Ranch. If I don't like the bitterness is there anything I can do about it now? Was it the green in the orange peals?
